M Q /l//IWMM `Ain a chimney above the Patented July 1l, 1933 UNITED STATES MICHAEL LEONARD, F ROLF-TTR NORTH DAKDTA CHlvINE-Y HEATER Application filed July 16,

My invention relates to a heater designed to receive its heat from a chimney, stack, smoke pipe, or the like.

ln accordance with my invention, l provide a heater lwhich may be installed as a and is intended to be permanent. rEhe heater embodies tubes or lines which may be removable for the purpose of replacement The tubes or lues may be surrounded by a jacket, which is preferably removable. The jac ret serves to cause a circulation of cool air from the room into the jacket, and from within the jacket into the room, and also serves to preventthe lianes from coming in direct contact with the lues. The heater is installed iireplace, such as in the second story of a building, and will elliciently utilize the heat contained in the smoke and products of combustion for heating the room in which the device is arranged.

In the vaccompanying drawings, Jforming a part of rthis specification, and in which like numerals are employed to designate like parts throughoutV the same,

In the drawings, wherein Jfor the purpose ot illustration is shown a preferred embodiment is a similar view of another gua-rd vthe lower 'box 19, connecting the bottom 25 1932. Serial No. 622,942.

of my invention, the numeral 10 designates a building or dwelling as a whole, having a first floor 11 and a second i'loor 12. The num eral 13 designates a brick chimney as a whole, comprising a iireplace 11, arranged within the iirst lloor 11 and alower chimney section 15 and an upper chimney section 1G. My heater is designated as a whole, by the numeral 17, and is arranged between thc chimney sections 15 and 16, and supports the upper chimney section 1G, as shown.

My heater comprises upper and lower boX- Y es 18 and 19, formed of heavy gauge sheet metal` or the like. The box 1S Yhas a bottom 20, and a top 21. The top 21 has a cenn trai opening 22, to register with the bore of the upp-er chimney section 16, the bricks of the upper chimney section resting upon the top 21 around the opening 22. ln order that there may be--no tendency for the top Q1 to bend downwardly near the opening 22,. I preferably provide spaced vertical struts which are rigidly attached to the top 21 and bottom 20, around the marginal edge ot the opening Q2. The bottom 2O is provided with openings Q4, iour of which are shown tor the purpose of illustration. The lower box or casing 19 includes a bottom 25 having a central opening 2G to register with the bore of the lower chimney section 15, this bottom resting upon the bricks constituting the walls of the chimney section 15. The box 19 includes a top 27 having openings 28 formed therein. Four of these openings 28 have been shown for the purpose of illustration, and these openings are in alignment with the openings 24. The openings 2,8 are surrounded by upst-anding iianges 29. Reintorcing struts 30 are also arranged within and top 27, to stiden the structure.

The boxes 18 and 19 are shown as square .in horizontal cross-section, for the purpose of illustration, and l employ four angle irons 31, arranged between the boxes 1S and 19, at their corners, an-d rigidly attached thereto by welding or the like. lt is preferred that the outer surfaces oi these angle irons be flush with the outer surfaces of the boxes. Diagonal brace rods 32 are preferably employed for connecting the angle irons, as shown.

Mounted within the openings Q4 of the upper box are vertically adjustable tubular couplings 33, having' flanges 34 at their upper ends. These couplings are designed to be permanent, and are formed of heavy gauge sheetmetal. The numeral 35 designates a plurality of vertically arranged pipes or tlues, such as ordinary stove pipe sections, and these pipes have their lo\ Yer ends mounted upon the tubular flanges 529, while their upper ends are inserted within the lower ends of the tubular couplings 33, which are then moved downwardly to snugly receive the pipes 35. It is thus seen that'when the pipes 35 become burnt or worn, they may be readily removed and new pipes substituted therefor.

The numeral 36 designates a shield as a whole, including plates 37, 38, 39 and 40. Each of the plates 37, 38, 39 and 40, is provided at one vertical edge with aY flange 41, bent at a right angle with relation thereto, and this flange has L-shaped slots 42 stamped therefrom, near its top and bottom. Each of th-e plates 37, 38, 39 and 40 is provided near its vertical edge, remote from the flange 41, with a pair of L-shaped slots 43. The several angle irons 31 are provided upon corresponding faces with studs 4G, arranged near their upper and lower ends.

The plate 38 may be applied to one side of the frame, then plate 39 arranged upon the next side, plate 40 upon the next side, and plate 37 upon the remaining sides. Each plate is moved downwardly so that the studs 46 will lock the plate to the angle iron. It is thus see that the several plates are removably lnounted upon the frame.

The plates 37 to 40, inclusive, constituting the shield, terminate beneath the upper box 18, leaving a space 45 for the escape of heated air, and also are spaced from the head 19, caving' a space 45, so that air may enter the lower wall of the shield.

It is to be understood that the form of my invention herewith shown and described, is to be taken as the preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoined claims.

Having fully described what I claim is:

1. A heater to he arranged between chimney sections, comprising upper and lower my invention,

spaced boxes, a framework rigidly connecting the spaced boxes, pipes arranged between the spaced boxes, vertically adjustable tubular couplings Connecting the upper ends of the pipes with the upper box, the arrangement being such that said pipes establish communication between the boxes.

A yheater to be arranged between chimney sections or the like, comprising upper and lower spaced boxes, a frame rigidly connecting the spaced boxes, a vertically adj ust able tubular coupling carried by the bottoni of the upper box and extending below the saine, a removable pipe arranged between the upper and lower boxes and having detachable engagement with the tubular coupling, and means whereby the pipe is detachably connected with the top ol' the lower box.

A heater to be arranged between chimney sect-ions or the like, comprising spaced upper and lower polygonal boxes, bars arranged at the corners of the boxes and rigidly connecting them, a plurality of pipes` arranged between the boxes and connecting them, the lower box having an opening in its bottom and the upper box having an opening in its top, and a shield surrounding the space between the boxes and secured to the bars.

4. A heater to be arranged between chimney sections or the like, comprising spaced upper and lower polygonal boxes, the lower box having an opening in its bottom and the upper box having an opening in its top, pipes arranged between the boxes and in communication therewith, lip-standing bars disposed at the corners of the boxes and rigidly secured thereto, said bars having studs, and a plurality of plates adapted to be mounted upon the bars, each plate having a flange at one vertical edge, said flange llaving L-shaped slots, each plate being provided near its opposite vertical edge with L-shaped slots, the arrangement being such that the several studs are adapted to extend through the slots in the plates and in the bars, and detachably lock the plates to the bars.

5. A heater to be arranged between chimney sections or the like, comprising spaced upper and lower polygonal boxes, pipe means connecting the boxes, a frame work rigidly connecting the boxes and a shield surrounding the frame work, said shield beingl spaced at its opposite ends from the boxes, affording inlet and outlet air passages.

In testimony whereof, I aflix my signature.

MICHAEL LEONARD.
